To all whom t may concern:

Beit known that I, J oHN J. MiLNEs, J r., a citizen of the United States, and a resident of the city of NewYork, Port Richmond,

borough of Richmond, in the county of Richmond and State of New York, have invented new and useful Improvements in Oil Burners, of which the following is a full,

provision of a simple and efficient burner which functions without the forming of a great amount of carbon thus eliminating the necessity7 for continual cleaning and allowing the operation of the burner without emitting clouds of dense smoke.

A further object of the invention isthe provision of an oil burner provided with means for automatically shutting ofiP the fuel supply when the burner ceases to operate.

Another object of the invention is the provision of a burner provided with auxiliary means for causingv the vaporization of the fuel so as to facilitate'the setting of the burner in operation, particularly when the atmospheric temperature is low.

These objects are accomplished by providing a casing in the lower p'ortionof which is an oil well having a baffle extending across the same, mounting above the oil well an annular plate so as to provide a combustion chamber above the oil well, mounting concentric with the oil well and:

combustion chamberan Vair pipe having an enlarged base, which in conjunction witlithe annular plate forms an opening the shape of a hollow circle, establishing communic'ai tion between the oil well and combustion chamber, connecting with the oil well means for supplying fuel, locating below Va gas burner for assisting in vaporiz'ation, and

' connecting with-the combustion chamber a drain pipe which conveys fuel from the burner to a means for shutting off fuel supply when the burner is not in operation. ,l

These and other objects ofthe invention will be more clearly understood fromthe following detailed description and accom-I panying drawings. K l

the lower portion of which an oilwell 16 isy formed and separated i fromrk a combustion,

chamber Q Sprovided in the upper portion of' the casing by jan annular' plate 13., The

annular plate v13 seats .onI shoulder' 14 extending circun ife'rentiztllyv about the ,casing and havinga circumferential groove 11, formed therein, ,for receiving l a Y circumfer-y ential bead.r llf2, .integral withjhe ,annular plate. Extending Vthrough wall of' `the casing 10, "establishing, communication between theY combustionchamber and the atmosphere'is a circumferential line of openthrough the'se' openings a 26 having an internal thread 25 is rotatablyy mounted` on an external thread 24:'providedonfthe casing 10. Attached to the/'ring 26 seivilylg its aln'iea'ns' for adjusting the same handle 27. Integral with the upper edgeofthe cas-` ing `1 0 is an annularplate 28zhavingla plu! ralityo'f air openings 2 9therein, said open-v ings being located in a circle.v j A plurality of openings 3 Oare also provided in' the plate 28 so that it may be attacli'edto the annular ings 15.; Inoder to control thefiiow of air lar basel9, the 'lower end ofwhicli'iis'thread- .l ed, isinounted in a threaded opening 1T- 'inl the bottom ofthe casing 10. The enlarged base i9 ,extends Slightly iiigh'erthan the annular plate 13 and Said annular pla@ forms aiannulaopaing.20, establishing communication betweenthe o il Well (16 .and ,th'e. combusbaii, .chamber 2 3- Thisffair Vpipe,allow sy.air tobehforced up-f ward" toy complete the combustion as thev gases reach the upper end of the air pipe. A spreader 33 carried by a rod 34 is mounted above the air pipe 18. The rod 34 is carried byV spiders 35 and 36 mounted in the air pipe 18. This spreader may be adjusted from beneath the furnace pot by meansY of'a handle 37 attached to the lower end of the rod 34. A pilot light 38 projects through the wall of the air pipe 18 near its enlarged base. This pilot light is connected by means of a pipe 39 with a gas main 40. In order to control the operation of the pilot light a valve 41 is located in the pipe 39.

A fuel supply pipe 42 leads through an opening 43 into the oil well 16. In order to provide for an even distribution of the Yoil throughout the oil well 16, a curved baille 44 is formed'integral with the bottom of the oil well and encloses a crescent-shaped area, into which the pipe 42 leads, between itself and the wall of the oil well. The baffle in conjunction with a portion of the wall of the oil well thus forms a container which upon flooding distributes the oil evenly through the remainder ofthe oil well. A ring 45 having a plurality of openings 46 therein is mounted in the oil well in line with the inner edge of the annularplate 13. In order to vaporize the oil supplied to the oil well 16 a burner 47 connected to the gas main 40 is mounted beneath the oil well by means of brackets 48 depending from the casing 10. This burner is very necessary in cold weather to provide a means for quickly setting the burner in operation.

A pipe 21 projects through lopenings 49 in the bottom of the casing 10 and an opening 22 in the plate 13. Connected to this vertical pipe is a pipe 50 which curves upward until its outer end is approximately in line with the upper end of the pipe 21. These pipes are provided to carry away the oil when the burner is flooded. A valve 51 is provided in the fuel supply pipe 42 and is operated by a lever 53. Suspended from the lever 53Vis a container 52 located to receive the oil from the pipe 50. Thus, if the burner ceases to function and oil continues to be supplied to the burner through the oil supply pipe 42, the oil is conveyed from the burner by means of the pipe 50 and emptied into the container 52. When the container becomes partially filled it operates the lever 53, closing the valve 51 and thus shutting offthe supply of oil. A valve 54is also mounted in the fuel supply pipe l42 in line with a valve 55 mounted in the gas main 40. These valves 54 and 55 are connected to a common lever 56 so that they mayy be voperated together. Y

The' burner is supported in the furnace pot 32 by attaching the annular plate 28 to the annular plate 31. As shown in Figure 1, the furnace has a water jacket 57 which serves as a means for heating water. This burner might be used for a number of different purposes.

In use and operation the valve 51 is normally open and to start the burner'the lever 56 is manipulated to close the valve 54 and open the valve 55 allowing a supply of gas to the burner 47 which initially heats the base of the casing 10, after which the lever 56 is manipulated to close the valve 55 and open the valve 54 whereby the oil is supplied to the well 16. The oil coming in contact with the heated base of the casing 10 will be vaporized and will pass up through the annular opening 20 where it is ignited by means of the pilot light 38. The vaporized oil passes up into the combustion chamber in a jet the shape of a hollow circle as spaced from the air pipe 18, since the base of the air pipe which defines the inner edge of the opening is of greater diameter than the remainder of the air pipe. Air is forced up through the air pipe 18 and is directed outward by the spreadei1 33. This prevents the'flame from impinging on the spreader and serves to spread it outward from the air pipe 18. Thus during the process of combustion the flame does not impinge on any metal parts and this eliminates the forming of carbon in the burner. Air for supplying oxygen for the combustion in the combustion chamber enters through the openings 15 in the casing `10. The process of combustion is completed at the top of the air pipe where a further supply of oxygen is provided.

In supplying the oil to the oil well the oil first enters the container formed by 'a por- Vtion of the wall and the baffle 44. As this container floods, the oil is distributed evenly throughout the remainder of the oil well, thus giving approximately an even depth of oil throughout the greater portion of the oil well.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated since manifestly the same can be considerably varied without departing from the spirit of the invention as defined in the appended claims.
